Pokémon Red and Blue randomizer code

This code allows the player to use an arbitrary code execution item as a wild Pokémon randomizer (grass and cave encounters supported), to be used with a bootstrap code to slot 3.

It uses OAM DMA hijacking to constantly write the random value of a d-sum address (specifically FFD3) in the main encounter table at D888.

Code

Upon using your arbitrary code execution item, the encounters are randomized until the game is powered off, but sprites are broken.

Item 3: Glitch item 0xC3 ("H" in Red, no legible name in Blue) x40

Item 4: TM11 x(any)

Item 5: (any) x (any)

Item 6: Glitch item 0x00 ("j.") x 0

Item 7: Thunderstone x136

Item 8: TM16 x240

Item 9: TM11 x1

Item 10: Potion x0

Item 11: TM05 x224

Item 12: Max Revive x33

Item 13: "PC" x255

Item 14: Lemonade x201

Item 15: Water Stone x 62

Item 16: Water Stone x34

Item 17: Lemonade x211

Item 18: Water Stone x62

Item 19: TM05 x 234

Item 20: "PC" x255

Item 21: TM01 x 97

GameShark codes

The following codes give the player a -g m (0x6A), which is automatically bootstrapped to item 6. Upon using it, the encounters are randomized until the game is powered off, but sprites are broken.
